Regional sand distribution of the Frio Formation is determined; depositional environments are identified; and the geopressured zone and its relationship to sand/shale distribution, growth faults, and fluid temperatures in the Middle Texas Gulf Coast are delineated. (MHR)
The development of field analytical and sampling equipment and techniques for the location of anomalies in surface water, stream sediments, and ground water which may indicate uranium deposits of commercial interest are summarized. Orientation studies are designed to identify the most effect hydrogeochemical, computational, and analytical techniques for reconnaissance survey. Nine orientation studies are in progress in Georgia, Pennsylvania, North and South Carolina, Tennessee, and Texas and the results obtained to date are reported. The equipment for neutron activation analysis of samples is complete and other analytical methods are being evaluated. Data management, analysis, and interpretation techniques are under development.

A preliminary study of the Frio sand distribution and formation temperatures and pressures was undertaken in order to define prospective areas in which a more detailed reservoir analysis is necessary prior to the selection of a site for a geothermal well. As a result two potential geothermal fairways were identified--one in the south part of the area in Hidalgo, Willacy, and Cameron Counties, and the other in the north part in north-central Nueces County.
